    selftest: Fix timestamps on FreeBSD 11
    
    FreeBSD's date does not print the %, and \? does not catch that
    
    Tested this manually:
    
    $ echo 'time: 2016-11-23 12:52:19.123456Z'| sed 's/\..*NZ$/.000000Z/'
    time: 2016-11-23 12:52:19.123456Z
    $ echo 'time: 2016-11-23 12:52:19.%6NZ'| sed 's/\..*NZ$/.000000Z/'
    time: 2016-11-23 12:52:19.000000Z
    $ echo 'time: 2016-11-23 12:52:19.6NZ'| sed 's/\..*NZ$/.000000Z/'
    time: 2016-11-23 12:52:19.000000Z
